Bacteriological Investigation of Aeromonas Hydrophila in Dairy Cattle: A Preliminary Study

Many different kinds of bacteria flourish in milk due to its almost neutral pH, high moisture percentage, and abundance of nutrients. Milk provides a perfect environment for these bacteria. The pathogenic A. hydrophila, capable of causing gastroenteritis, can potentially be transmitted to people through milk. This study purposed to explore the prevalence of Aeromonas hydrophila in certain dairy farms, as well as its culture characteristics and biochemical identification. There were positive 22 milk samples of cattle origin out of 380 milk samples examined and the prevalence of Aeromonas hydrophila was 5.8%. The identification of A. hydrophila was assured consistent with phenotypic characteristics on specific culture medium and the diagnostic biochemical reactions. The possible risks to public health posed by Aeromonas species found in milk and its derivatives, as well as the potential methods that could be used to combat these risks, have been considered.
